Tisch SKU: SF18321

Tisch Scientific PTFE Syringe Filters, 0.8 µm, 13 mm, 100/Pk - SF18321

Tisch Scientific carries a broad filtration catalog covering membranes, devices, and consumables for the laboratory. Sample preparation for chromatography often ends with a syringe filter on the path to the vial. Hydrophobic PTFE repels water while passing gases and solvents freely and stays chemically inert against solvents, acids, and alkalis. The PP housing sustains efficient flow on viscous samples while staying inert across common laboratory solvents and prevents sample bypass under rated operating pressure. When sterile or particle-free preparation matters at the bench, the syringe filter delivers it with minimal added handling.

Technical Specifications

• Filters aggressive organic solvents without swelling or breakdown
• Stable across a wide operating temperature range for demanding methods
• Chemically inert against aggressive solvents, strong acids, and alkalis
• Hydrophobic membrane repels water for gas, vent, and solvent filtration
• Low extractables keep the chromatographic background clean

Housing Specifications

• Thermal-bonded construction keeps adhesives out of the fluid path
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Optimized internal geometry minimizes backpressure in service
• Stable across the full aqueous pH range in routine sample work

Clarifying organic mobile phases before injection protects your chromatography while standing up to the solvent. Solvent-stream filtration handles the solvents and reagents your methods rely on from organic mobile-phase prep through reagent clarification.
